  • Publication number: 20090226355
    Abstract: Methods of producing semiconductor materials via polymerization techniques are provided. The methods include reacting a precursor compound containing a metalloid semiconductor element, such as silicon or germanium, with a catalyst to form a polymer composition. The polymer precursor is then decomposed to form an electrically conductive hydrogenated composition containing silicon or germanium. The methods employ relatively safe raw materials and products and result in high yield reactions. Moreover, the polymers can be applied in liquid form and can be used as an “ink” or liquid to selectively coat a substrate.
